Abstract
A public key service determines a seed value used by a sending device to generate a one-time signature (OTS) private key that the sending device uses to digitally sign a message before sending the message to a receiving device. The public key service generates, based on the seed value, a public key used to authenticate the digitally signed message as having been sent by the sending device. The public key service receives a request for the public key from the receiving device, and in response sends the public key to the receiving device, such that the receiving device is able to authenticate the message.
